Measurement of Portal Pressure [PDF]
Clinics in Liver Disease, 2014 Portal pressure is estimated through measuring the hepatic venous pressure gradient (HVPG). The main clinical applications of HVPG measurements include diagnosis, classification, and monitoring of portal hypertension, risk stratification, identification of candidates for liver resection, and monitoring efficacy of β-adrenergic blockers.

Surgery Today, 1994
Portal pressures were estimated non-invasively in 100 patients who underwent hepatic resection and completely fulfilled the 21 variables evaluated. Ten variables were selected from among all those in the univariate analysis, and a stepwise discriminant analysis revealed four independent significant variables, namely: The indocyanine green dye retention

Aliskiren reduces portal pressure in portal hypertensive rats
European Journal of Clinical Investigation, 2011Eur J Clin Invest 2012; 42 (5): 526–533AbstractBackground Aliskiren is a direct renin inhibitor used in the treatment for arterial hypertension. It can also augment nitric oxide (NO) production, which plays a crucial role in the pathogenesis of portal hypertension and modulation of porto‐systemic collaterals.

Portal venous pressure in biliary atresia
Journal of Pediatric Surgery, 2012Biliary atresia (BA) is characterized by a variable degree of fibrosis within the liver, causing portal hypertension sometimes evident at the time of presentation.The aims of this study are to measure portal venous pressure (PVP) at time of Kasai portoenterostomy (KP) and to investigate the value of surrogate indices.At the time of KP and before any ...

Endoscopic Ultrasound Evaluation of Portal Pressure
Clinics in Liver Disease, 2022Portal hypertension is a complex syndrome with multiple clinical manifestations that develop in a variety of conditions and diseases. The spectrum of portal hypertension manifestations is wide and dependent on the physiologic site of increased portal resistance (pre-, post-, and sinusoidal or intrahepatic), as well as the presence of hepatocellular ...

Reflections of Pressure Waves at Tunnel Portals
Journal of Sound and Vibration, 1994Abstract Reflections of plane waves from the open ends (portals) of axisymmetric pipes and plane two-dimensional (2-D) channels are investigated analytically, numerically and experimentally. An analytical approach developed by Rudinger [1] for pressure decay at an axisymmetric, flanged portal is extended to longer times, and equivalent analyses are ...

Fructus aurantii reduced portal pressure in portal hypertensive rats
Life Sciences, 1995The purpose of this study was to investigate the effects of Fructus Aurantii (the unripe fruits of Citrus aurantium L.) on portal hypertensive rats. Portal hypertension was induced by partial portal vein ligation (PVL) in Sprague-Dawley rats. Sham-operated (Sham) rats served as controls. Hemodynamic and in vitro contractile studies were performed at 14
